Kristen Stewart was one of many celebrities who took part in the 12-12-12- Hurricane Sandy Benefit yesterday, with the singer giving a poignant speech to encourage the public to donate to the relief efforts.

The Twilight actress appeared a little nervous as she delivered the speech to the huge crowd at New York City's Madison Square Garden, dedicating most of the speech to New Jersey which received $37 billion worth of damages by the Hurricane which hit in October.

Introducing Kristen to the stage, actor Billy Crystal said: "She flew in from California just to be here tonight because she wanted to help out.

"She got here in three seconds because that's what vampires do when they fly at night, they go very fast...Please welcome, a fantastic young actress, please welcome Kristen Stewart!"

Taking to the stage in a neon playsuit, Kristen began: "I am here to talk to you about New Jersey tonight," before going on to read out a list of statistics about the damage caused by the disaster.

"Now is your chance to be Jersey strong with us," Kristen added asking the public to help with the relief.

Other celebrities to take part in the concert included Susan Sarandon, Adam Sandler and Chris Rock, while the likes of Bruce Springsteen, Kanye West and The Rolling Stones performed during the night.

No doubt the appearance will help improve Kristen's public image, which was damaged earlier this year when she admitted to cheating on boyfriend and Twilight co-star Robert Pattinson with Rupert Sanders, who directed Snow White and the Huntsman which she starred in.
